Few brands can sell luxury as a necessity and get away with it like Porsche. A recent ad for the new Porsche 911 reads: “…You strain to think of something else that has stayed this true to its ideals for 46 years. You come to the realization that, in the age of the superfluous and superficial, the unrooted and the unserious, the 911 is necessary. Very necessary. The Porsche 911. There is no substitute.”
